ST3237EB数据手册集成电路（IC）的驱动器接收器收发器规格书PDF

描述 Description

The ST3237E is a 3V to 5.5V powered EIA/TIA-232 and V.28/V.24 communication interfaces high data-rate capability and enhanced electrostatic discharge (ESD) protection at ±8 kV using IEC1000-4-2 contact discharge and ±15kV using Human Body Model (HBM). The other pins are protected with standard ESD protection at ±2 kV using HBM method. The ST3237C is a transceiver (5 drivers, 3 receivers) for fast modem applications.

The device has a proprietary low-dropout transmitter output stage providing true RS-232 performance from a 3V to 5.5V supply using a dual charge pump. The device is guaranteed to run at data rates of 250 kbps in the normal operation mode and 1Mbps in the very high speed operation mode while maintaining RS-232 output levels.
